a pair of fuzzy dice hang from your mirror. While you accelerate from a stop on a horizontal surface to 28 m/s in 6 s, what angle θ does the string make with the vertical?
tan θ = Y/X
a = ΔV / Δt
The Attempt at a Solution
Just want a double check:
So we can use the accelerations to figure out the angle....
Ay = 9.8 m/s^2
Ax = (Δ V)/ Δ (t) = (28 m/s - 0)/(6 - 0) = 4.7 m/s^2
tan θ = 4.7 / 9.8 = 25.6°
